Have a similar problem. Up until now I worked as a contractor (not IT), to maintein a sense of independence at to keep my options.
But when I come home, I'm so tired, drained and just want to forget about all the crap that is going on at work that I distract myself with anything I can get my hands on, books, video games, videos, surfing...
So I get less of my own stuff done.
So I'm stuck in this situation.
